Candle Stick Chart JS Plugin

Bellow is a line chart. I am trying to convert the unix time using Seconds to Date plugin and it kind of works as it is not showing the correct data - I always get the year 20.01.1970.
Bellow are 2 questions I have:
How to fix the timestamp issue?
How can I modify the design of the element displayed when hovering over the chart?

Any help would be greatly appreciated!

You might want to check the plugin details or the plugin element’s appearance tab to check if you can modify the tooltip’s design. Most chart plugins, especially Bubble’s chart elements have very limited design functionality :grimacing:

Which seconds to date plugin are you using?
